STORAGE BATTE RY.V

SPECIFICATION forming part of Letters Patent N0. 765,082, dated July12,1904.

Application filed August 9, 1902.

To 'I1/ZZ wit/)m t may concern- Bc it known that I, IsIDoR KITSE u, acitizen of the United States, residing at Philadelphia, in thel countyof Philadelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Storage Batteries, of which the following isaspecification.

This invention relates to improvements in electrical accumulators, or,as more commonly known, storage batteries.

' In that class ot batteries wherein the electrodes are formedof leadplates to which is applied a suitable' coating of active material,

usually oxid of lead, it is a well-.known fact that the exposed surfacesof the lead become in time unduly brittle and warped, and, moreover, itis also a well-known. fact vthat batteries of the class referred to areextremely cumbersomeand heavy andV that their capacity is comparativelysmall in proportionto their great weight. i

It is therefore the object fof the present invention to provide astorage battery the construction of which is such as to eftec'tuallyovercome the objectionable features above noted and one which is oflarge capacity, but at thesame time much lighter in proportion toitscapacity than the batteries now generally in use. l i y With thesegeneral objects in View and others which will appear as the nature ofthe improvements is better understood the invention consists,lsubstantially, in thenovel construction, combination, and arrangementofparts as will be hereinafter fully described',

illustrated in the accompanying drawings, and

pointed out in the appended claims.

In the drawings, Figure l is a vertical transverse sectional View of .abattery conthe battery removed from the containing-jar,`

the side cover and the 'active material being removed. Fig. 3 is asectional perspective L View of the frame of the battery. Fig. 4 is theusual containing-jar.

tive view thereof. specti've view of the frameof the form shown .inFigs. 5 and 6, and Fig.' 8isjatop plan view of such form. Referring tothe drawings, the numeral l designates tlie usual containing jar orvessel ot' a storage battery; but as this does not enter into'thepresent invention it is suiiicient to state that the same may be of anydesired construction and form.

Arranged within the containing jar or vessel 1 is a cell 2, and saidcell comprises a frame 3, which is substantially rectangular in form.The frame 3 is preferably formed of hardrubber or other material whichwill not be attacked by the electrolyte within the containing jar orvessel, and said frame is.

provided at each of its edges and xextending entirely around the samewith a rabbeted portion 4, through the medium of' which a shoulder 5 isformed at such edges. is also providedl at its central portion and ex-The frame-3y The slots 7 reg-- Fig. 7 isa sectional pertending entirelyaround the saine with an in-r terior thereof, as will appear more,-fully here` inafter. .l

Arranged within the'frame 3 at the sides of the iange' or bead 6 anditting snugly there againstis a pair of suppbrting-plates 8, and

said plates are formed of porous .material in' -order that theelectrolyte conlined within the area `between said plates when the cellis placed within the containing jar or vessel 1 may be absorbed by saidplates and passed therethrough. The plates 8 are also lproviole'i'4 attheir outer faceswith of outWtIdly- .projecting 'pins 9, 'said pinsbeing-:arranged preferably in staggered relation inf' order to providesupports for a conductorj l0. The

conductor 10 is-infthe form of a thin strip,

preferably of lead, and s aid conductor is wound about the pins 9 in. aeircuitous manner, as

clearly shown in Fig. 2, and arranged on said Fig. G'isaperspecpins insuchfmanner that the outer edges' of IOO ' said pins and strip in suchmanner as to 'completely'envel'op the same, and in order that the activematerial may be held vwithin the frame 3 andupon the plates 8 said frameis provided with removable covering-plates 13.

The latter, as is the lcase with the plates 8, are

, formed of a porous material through which the electrolyte may readilypass in order to reach the active material; but it will be observedthatthe length .of the pins 9 and the. width of the strips 10 are no tsufcient to contact with the inner sides of thel plates 12.

:Hence'a space remains between said plates ycontaining jar lor vessel 1.

Aand the extremities of the pins 9, which spaces are lfilled with'theactivelmaterial 12, as is clearly seen Vin Fig. 1. 1

In Figs. 5 to 8, inclusive, is shown another form of' the battery, andthis form is designed for use without the employment of the usual Theform shown in the figures referred to is precisely the same in allrespects to the form shown in Figs. 1 to L1, inclusive, with theexception that in lieu of providingr the bottom of the containing-frame3 with a slot, as is the casein the form shown in Figs. 1 to 4, such'slot is entirely omitted, so that the lower end of the frame remainsclosed. In this ferm the electrolyte is placed within the cell throughthe slot7 at the upper end thereof and occupies the space between .thesupporting-plates 8, and it wcill also be observed that in lieu offorming the-coveringplates 13 of porous material such plates are formedof a non-porous material. Consequently the electrolyte is precludedpassing through -the covering-plates, and hence lealiage of the cell isentirely prevented.

It is obvious that in each of' the forms of. the invention shown one ofthe supportingplates 8 and its pins 9 and conducting-strip 10 will formthe 4positive electrode, while the other` supporting-plate and its pinsand conducting-strip will form the negative electrode,

and by reason of the construction shown and described it is also obviousthat a battery is provided which is comparatively light, but of greatcapacity, and one in which there are no exposed surfaces of lead tobecome in time unduly brittle and warped.

While the forms o-f the invention herein shown and described are whatare believed to be preferable embodiments thereof', it will of course beunderstood that the same are sus-` ceptible of various changes in theform, proand the right' is therefore reserved to modify or vary theinvention as falls within the spirit and scope thereof.

Having thus described my invention, what is claimed as new, and desiredto be secured by Letters Patent, is

7 1. A storage battery, comprising a containing-.frame provided with aninlet for the electrolyte, a support arranged therein, a conductorcarried by said support, and a body of active material confined withinsaid frame and enveloping said conductor.

2. A storage battery, comprising a contain- 'ing-frame, a supportarrangedltherein, a series of pins carried by saidsupport, a conductorcarried by said pins, and a body of active material arranged within saidframe and enveloping said conductor and pins. l

3. A storage battery, comprising a containing-frame, said frame beingprovided lwith an internal iiange or bead, supports arranged within saidframe and fitting upon said fiange4 or bead, conductors carried by saidsupports, and abody of' active material confined within said frame andenveloping said conductors. 4. A storage battery,l comprising'acontaining-frame, .said frame beingprovidedwith an internal Harige orbead having an inlet for the admission of' the electrolyte, supportsfitted upon said flange or bead and spaced from each other to provide aconfined area for the elec'- trolyte, -conductors carried byl saidsupports, and a body of active material confined Within said frame andenveloping said conductors.

5. A storage battery, comprising a containing-frame, said frame beingprovided with an internal flange or bead and having an inlet forthe-admission of the electrolyte, supports {itted upon said iiange orbead and spaced from each other to provide a confined areal for theelectrolyte, pins carried by said supports, conductors carried by saidpins, and avbody'of active material confined within said frame andenveloping said pins and said conductors.

6. Astor-age battery, comprising a positive and negative electrode, bothelectrodes contained in one containing-frame provided with an inlet forthe electrolyte, and 'a porous support for the conducting and activematerial lfor each of said electrodes.
